Is there a word for a "partial anagram"? By that I mean a word that can be made from some of the letters of another word, but not necessarily all of them (that would be a normal anagram). For example, HORSE contains the words ROSE and ORE among others. Is there a word for what ROSE and ORE are in relation to HORSE? Also, is there a website that will list all "partial anagrams", or whatever they're called, of a word? Thanks a lot.
